Oxo-complexes of rhenium(V)

Abstract

Improved methods of preparing salts of the oxopentachlororhenate(V) ion, [ReOCl₅]^2–, are given and the magnetic properties of Cs₂ReOCl₅ are discussed. The hydrolysis of rhenium pentachloride in the presence of triphenylphosphine leads to the formation of rhenium(III) complexes. The reaction products of trans-dioxobis(ethylenediamine)rhenium(V) chloride with hydrochloric acid are reformulated. The visible spectra of some trans-dioxo-, oxohydroxo- and bis(hydroxo)rhenium(V) compounds are discussed.
